Short answer: the Marshall Kilburn II. It ranks #42 of 120 large speakers by sound quality, rated 3.8/5, at $219. The Treblab HD-Max ranks #104, rated 2.4/5, at $123.47, $95.53 cheaper, a saving that is not big enough to make up the sound-quality gap.
The Marshall Kilburn II is the better-sounding pick. A rugged Marshall styled stereo speaker with a leather handle, quick charging and a sound that suits rock. The catch: Boosted upper bass, not very detailed, not as deep bass as competitors, upper mids peak.
The Treblab HD-Max is the tougher pick. A very loud, well built boombox with a long tested battery, water resistance, and power bank charging. It is rated IPX6 against IPX2 for the Marshall Kilburn II. The tradeoff: Boosted upper bass, not much lower bass.
Buy the Marshall Kilburn II. It is rated higher for sound quality, and saving $95.53 with the Treblab HD-Max does not make up for the sound-quality gap.
